Think before you print…

I would dedicate this Blog for the environment. I am someone who never thought about the environment, for example I always used to throw the paper plates I eat and cool drink bottles I drink out of my car onto the road without even thinking, What am I doing? I never felt it wrong until I had a friend, who doesn’t like to do that. After her warning me few times I realized what I am doing. And now I don’t drop them out but drop them in a dust bin.

 

It’s a very small thing which we need to do and these small things would cumulate to make a difference. I would also say that we need to educate people around us that small things make a big difference. So my Blog today would be part Technical and part Nature Saving.

 

I would like to talk about Printers and printing. What is the cost of an Inkjet Printer? The answer would be a few thousand rupees depending on the functionality of the printer. What is the cost of the Ink Cartridge? The answer would be a few thousand rupees depending on the make and model of the Cartridge. I have seen printers in the market which sell for 3000 INR and the cost of the Ink Cartridge would be 2000 INR. So is the actual cost of the printer 1000 INR.

 

The answer would be No. The Printer manufacturers actually sell the printer at a loss and would make up by selling the Ink Cartridges. On an average an Inkjet Printer Cartridge would last for around 500 prints or 6 Months. So if you buy a printer and use it for 3 years you are actually paying him 3000+12000=15000 INR.

 

You might say that we can use off-market or refilled cartridges, then you need compromise on print quality and manufacturer warranty for your printer. So when are you thinking of buying a Printer choose Laser over Inkjet. Because laser printers use Toner in place of ink and would last few thousand copies compared with the few hundred copies inkjet cartridges last.

 

Also make it a habit to print on both sides of the paper. Agreed it would need some effort if you don’t have a printer that supports duplex printing, but you can always print odd pages first and then print the even pages.

A blog on Windows…

What is an Operating System? A good answer would be “A set of programs that provide a GUI to interact with various devices in a computer”. This definition would hold good until a few years back, when an operating system is just a few icons and menus that you see when you switch on your computer. Operating systems provided file and device management using a Basic GUI.

 

But with the development of computers, operating systems also evolved a lot. From simple file and device management solution, modern day operating systems should be stable and secure the data stored on a computer. The data stored on a computer can be anything from music, movies and photos to data that you have generated and stored in different files. It takes only a small virus, a power surge or a device failure to destroy data.

Today’s operating systems try to anticipate such scenarios and issue warning messages and take pro-active steps to minimize the data loss. I would talk about Windows XP and Windows Vista because 80% of computers run on Windows Operating system and Windows Vista is an upgrade to Windows XP.

Windows XP has been around for 8 years now and in considered one of the best operating systems released by Microsoft. When Windows XP was released it was considered a resource hogger. Windows XP required 128 MB of RAM to run smoothly. And there are many complaints from long installation times to frequent crashes. Microsoft released Service Pack 1 and things changed. Most of the security holes are fixed and Windows XP became stable. Windows XP was built to give a better user experience by easy installation and plug & play capability.

After a few years with XP, internet threats have grown and Microsoft started bundling Anti-spyware products along with Windows XP. This didn’t help much, and since Windows XP is the most used, hackers tried to find ways to break into Windows XP systems. This triggered the need for a more secure operating system and there came Windows Vista into picture.

Some of the problems with Windows XP are that password protection is not secure enough, users can use Bootable live CD’s like miniPE or Road Starter to bypass Passwords and access the file system. The other major issue is Internet Explorer 6 which is the number one target for hackers. By exploiting the security homes in IE6 hackers can take control of IE and hence the Windows XP box. And last but not least, when you try to search for a file under Windows XP, you have a terribly slow search tool.

Now its Windows Vista which is structurally more robust and is much more visually appealing. Vista comes with Encrypted File System (EFS) which takes care of file level security. Vista allows one to encode an entire partition or hard disk with just a few clicks. In Windows Vista Internet Explorer runs with restricted permission. If a malicious piece of code enters the system through the browser it cannot do much harm, since Vista simply refuses to permit to run it. File Searching has improved a lot with Vista.

But 2 of the night mares with Vista are getting your old hardware running and the annoying popup prompting you to allow or block any action you have performed.

Photography as a Hobby: Choosing a Digital Camera

Happy Valentine Day…to everyone…..Since today is Valentine day I have decided to blog on something other than computers…I have 2 options to choose from Nature and Photography, oops I should say 3, I have left out my desire for Cars and Driving. I have chosen to blog on Photography. That’s something which I am trying to work on these days.  

I have started Photography with a Kodak film camera later upgraded to a Yashika Camera, then was pulled into Digital Photography, I have used the first digital cameras from Sony which were 2-3 Mega-Pixels with 16-32 MB Compact Flash cards, later upgraded to a 5 Mega-Pixel Canon with a 512 MB Card. I was never a serious photographer until I bought an Olympus 710 a year ago, the photos I shot using the camera had tempted me to take photography as a hobby. Unfortunately I lost my Olympus 710 in my trip to Singapore and I have replaced with a Olympus 280, which is an 8 Mega-pixel one. I am looking for a DSLR and it’s in my wish list.  

If you are someone like me using a Digital Camera for 1-2 years now, then your next step would be to buy a Digital SLR camera. But, Which One? Would be very hard to answer. There are so many products out there offering a variety of Technologies. In this blog I will try to explain the knowledge I have gained in the last 6 months trying to find out the Digital SLR which fits my budget and passion. 

First question would be what should be the Mega-Pixel rating of my Digital SLR? Few people would say 8 or 10. And most if them would say the latest available in the market. I need your answer to another question to answer the above question. What are you going to do with the photos taken by the Digital SLR? If you want to take photos of ur friends, trips, function and post those photos on the web, e-mail them to friends or order small prints and put them in album, then a 2 mega-pixel cam would be more than enough for your needs. Entry level Digital SLR cameras start at 6 mega-pixels. Therefore if that’s all you want to do with your photos, the mega-pixels rating of your Digital SLR does not need to be a major concern. But, if you want to print large posters, you need a higher mega-pixel rating on your Digital SLR. All entry level SLR’s produce very good quality photos up to a certain size, more pixels gives you more freedom to enlarge even more.  

Which brand should you go with Canon or Nikon? Are you surprised that I have used only 2 names? Are these the only 2 brands that produce Digital SLR’s?  

The answer is pretty simple, these are the most popular brands and have most of the market share, but not all cameras from Nikon and Canon are great. Both the companies have produced some excellent and some ordinary brands. When buying a DSLR you should look for build quality. Observe the number of metal parts and the no of plastic parts in the camera body. Metal parts can be replaced, while plastic parts are not replaceable. So if the plastic part gets damaged you cannot get a replacement, you need to get yourself a new DSLR 2-3 years down the line. Next this is to check the feel of the Camera in your hand. You can feel the quality of build by holding it in your hand. Quality between brands is almost the same for the low end DSLR’s. However if you decide you don’t need a higher end camera, you can check other brands like Sony, Olympus etc. 

What features should I go for?  

Features can vary between the basic things like 6, 8, 10, 12 mega-pixels and Auto Dust Cleaning to advanced features like Live-View etc. To make things even worse each manufacturer gives a different name for the same technology. You need to do some research on the internet before taking the final decision.

I am tempted to give the url of http://www.cameralabs.com which is one of the best site I have found for camera review.  

Check this site when you are buying, also remember that when you buy a DSLR you need to buy a good lens or two to complement your DLSR.

How to troubleshoot your Mother Board?

Troubleshooting is the process of knowing the issue; determine the reason for that issue, finding a fix for the issue, applying the fix, then checking if the fix has fixed your issue. These are the steps you need to check before you fix any issue and putting everything back to normal. Before starting the process make sure that the issue has not resulted from a change in options in Windows Settings or BIOS or some Virus or Spyware activity.


Your mother board is the backbone or nervous system of your computer, every device in your computer depends on your mother board to ensure optimum functionality. It connects all the devices in a PC and checks that devices are communicating effectively between them. Common sign’s of mother board failure are that the PC won’t boot, doesn’t reach the BIOS test screen, scrambled text during and after the BIOS text screens, unusual system hangs, different combinations of devices not working.

Since all the devices are connected to the motherboard certain devices may not work if the mother board is having issues so be sure to test those devices before throwing then out and buying new devices.  First step would be a inspection of the mother board, to make sure all cables are connected properly, the fans are running at optimal speeds, and that the BIOS battery is working.

If the cables are not connected properly, the mother board may refuse to start. For example in some old mother boards you can connect the IDE Cable in the wrong direction. Ensure that PIN 1 on the mother board matches with the Color Coded Wire on the Hard Disk Cable.

Dying fans are another cause for mother board issues. An old fan would operate at lesser RPM and might not provide sufficient cooling for the CPU, and if the CPU temperature reaches a Particular level the Mother Board would halt the system. Also check for any broken or leaking capacitors and burn spots on the back of the mother board, these can immediately render a motherboard useless.  

Other major reason for Mother Board failure would be an ageing SMPS Units. You can test your power supply in 2 ways. There are software’s like Mother Board Monitor and ASUS PC Probe (works only with ASUS MB) which would give you details about the Voltages being used by the Mother Board or you need to get a spare SMPS and test it by swapping with your current SMPS.

If you can borrow a friends mother board you can try exchanging the motherboard with yours to see if it resolves your issues, if your PC works fine then you need a mother board replacement. If you think the motherboard is faulty and it is still in warranty you should be able to send it back to the manufacturer for a new one. Ensure that when you buy a mother board you should keep all of the packing and the box and warrenty cards, and there would be some labels that will bar the warranty if tampered with make sure you do NOT tamper them.

Which is the best anti virus program now?

Symantec, McAfee and Trend Micro are the Big 3 in the Antivirus Industry. They have several products which deliver.

In my 10 years of computer experience, in which i sold more than 200 computers, installed more than 1000 Computers and trouble shooted countless computers, i always feel that what ever the antivirus it should have the Latest Definitions to provide effective protection.

It’s hard to clean a file which is infected with virus, so you should make sure that the virus doesn’t enter your system in the first place. For this you need to install the antivirus with the current definition files before connecting to the internet or opening any CD which you bought from your friend.Norton is very slow, i have heard this from majority of my customers, but they should understand it depends on which version of Norton you are using. People generally use Norton Internet Security which is basically just not an Antivirus, but firewall, IDS, Antivirus and Anti spam in one application.

So when you compare running the above against AVG Antivirus which is a Virus only scanner your system would be definitely slow. But you should also take into account the protection if offers.

My first choice would be Symantec Antivirus Corporate Edition 10 if you want a Virus and Spyware solution and Norton Internet Security if you want all in one solution. But remember Symantec, McAfee and Trend Micro charge for subscription to get the updates.

I have used AVG in some cases and would give a 5 Star rating for its abilities.

If you want to pay for your Antivirus go with Symantec or McAfee. Free would be definitely AVG. If your system is infected with Virus and won’t allow the existing Antivirus to run a scan and won’t allow installation of New Antivirus you can use McAfee Stinger.

 

 

It’s a single EXE file which would run and clean the Viruses. You can copy the EXE file to a boot CD and run the Application booting of the CD and running. This would allow the EXE to run and clean viruses without loading the Windows file system and hence effective cleaning.

Above link would allow you to download Stinger and has instructions on how to use it.

If you need any further clarification please get back to me.
